EastEnders star Tamzin Outhwaite was introduced as DCI Sasha Miller at the end of Series 10, joining Nicholas Lyndhurst, Denis Lawson and Dennis Waterman as the team of retired ex-coppers reinvestigating the Met’s unsolved crimes.

Executive producer Richard Burrell commented: “The end of the last series was very much about Tamzin’s character getting her feet under the table as the new boss of UCOS. The starting point for this series is, its six months later, they know each other, they know how to rib each other, they know how to wind each other up and they’re up and running to have new adventures.”

He added: “The other point about the new series is with the new team in place we go back to 10 separate stories, with a variety of character issues weaved throughout each episode for one, or all, of the main cast. It’s also an opportunity for the audience to get to know and fall in love with each of the characters.”

Producer Tom Mullens explained: “There’s definitely a new dynamic within the team, the format is still the same with three unruly boys running rings around their boss. Tamzin’s character brings something slightly different to the dynamic and so do the guys and there are different relationships to explore between them all.”

Hinting at Series 11’s storylines, Burrell teased: “In episode one we concentrate on Gerry Standing’s character and his upbringing in Bermondsey, the people he used to know… We meet Steve McAndrew’s wife, played by Julie Graham who has to deal with his son who turns up unexpectedly, Sasha Miller has to deal with her ex-husband, who is also a cop and Dan is dealing with empty nest syndrome when his daughter leaves for university, so we play those character stories throughout.”
